* [PATCH] net: ethernet: ti: davinci_cpdma: fix fixed prio cpdma ctlr configuration
From: Ivan Khoronzhuk @ 2016-11-08 13:10 UTC (permalink / raw)
To: mugunthanvnm, grygorii.strashko, netdev
Cc: linux-omap, linux-kernel, Ivan Khoronzhuk
The dma ctlr is reseted to 0 while cpdma start, thus cpdma ctlr
cannot be configured after cpdma is stopped. So, restore content
of cpdma ctlr while off/on procedure.
Based on net-next/master

For the sfc change:
Acked-by: Edward Cree <ecree@solarflare.com>
And I accept that "suggests" isn't needed and the current "imply" semantics
are probably fine. If not we can always change it or resurrect "suggests".

Only the first fragment will be considered UDP, it will treat the rest as "other
IP" and 2-tuple hash them, probably hitting a different queue.
My understanding is that while that will reduce performance, that shouldn't be a
problem as performance-sensitive users will avoid fragmentation anyway.
It could also lead to out-of-order packet delivery, but it's UDP so that's
supposed to be OK.

Hi Ross,
Can you try this patch and let me know if it helps:
http://git.linux-nfs.org/?p=anna/linux-nfs.git;a=commitdiff;h=bb29dd84333a96f309c6d0f88b285b5b78927058
I'm planning on sending it to Linus soon, so it should be in rc5.

Hmm...that said though, there are some other suspicious accesses
of xpi_xpswitch. Looks like these are called without the rcu_read_lock
clearly being held:
rpc_clnt_xprt_switch_add_xprt
rpc_clnt_xprt_switch_put
...though it's possible I missed something there.

Thanks Ross,
----------------------8<----------------------
bool rpc_clnt_xprt_switch_has_addr(struct rpc_clnt *clnt,
const struct sockaddr *sap)
{
struct rpc_xprt_switch *xps;
bool ret;
xps = rcu_dereference(clnt->cl_xpi.xpi_xpswitch);
rcu_read_lock();
ret = rpc_xprt_switch_has_addr(xps, sap);
rcu_read_unlock();
return ret;
}
----------------------8<----------------------
Looks like the simple fix is to just move that rcu_dereference call
inside the rcu_read_lock there.

Sounds very good. And we may also need features bits
(VIRTIO_NET_F_GUEST|HOST_GSO_X) for this.
This is in fact one of items in networking todo list. (See
http://www.linux-kvm.org/page/NetworkingTodo). While at it, we'd better
support not only VXLAN but also other tunnels.
We can start with the spec work, or if you've already had some bits you
can post them as RFC for early review.

* [PATCH v2 3/6] qedi: Add QLogic FastLinQ offload iSCSI driver framework.
From: Manish Rangankar @ 2016-11-08 6:57 UTC (permalink / raw)
To: martin.petersen, lduncan, cleech
Cc: linux-scsi, netdev, QLogic-Storage-Upstream, Yuval.Mintz
In-Reply-To: <1478588223-16183-1-git-send-email-manish.rangankar@cavium.com>
The QLogic FastLinQ Driver for iSCSI (qedi) is the iSCSI specific module
for 41000 Series Converged Network Adapters by QLogic.
This patch consists of following changes:
- MAINTAINERS Makefile and Kconfig changes for qedi,
- PCI driver registration,
- iSCSI host level initialization,
- Debugfs and log level infrastructure.

Hi David,
I think that it is important to notice that the RFC says also
that only the first matching rule is applied.
"
When new Query with the Router-Alert option arrives on an
interface, provided the system has state to report, a delay for a
response is randomly selected in the range (0, [Max Resp Time]) where
Max Resp Time is derived from Max Resp Code in the received Query
message. The following rules are then used to determine if a Report
needs to be scheduled and the type of Report to schedule. The rules
are considered in order and only the first matching rule is applied.
1. If there is a pending response to a previous General Query
scheduled sooner than the selected delay, no additional response
needs to be scheduled.
2. If the received Query is a General Query, the interface timer is
used to schedule a response to the General Query after the
selected delay. Any previously pending response to a General
Query is canceled.
"
So I would read the above like below:
If some general query arrives and there is some
already pending response scheduled sooner,
no action is needed.
That is how I understand to the rule [1].
But when an general query arrives and there is some other
response already pending, but not sooner as rule one says but later,
new report should be scheduled and the already pending one
needs to be canceled.
That is how I understand to the rule [2]
If there is no already pending report scheduled
the first part of the rule [2] is applied
and new report is scheduled along the selected delay.
So basically we need to compare the already scheduled response exp time
with the one coming in and choose the sooner one.
This is exactly what the patch does.
What do you think?
Best regards Michal Tesar

Thanks Stephen,

Okay, so klcc is missing:

...
And this is where I gave up (at least for now) - it is because I have not
installed my kernel using the packet system - that is my fault and I will get it
fixed.
I did see that you wrote in the readme.md that this needs to run as root - but
it did not look like a permission issue...
So, not very usefull feedback - I know - sorry.
I will get this fixed, give it another try and the get back to you.

This clearly shows that the older userspace interface, of tx_queue_len
having double meaning, was a mess!

No, you will still end-up with "noqueue". It is now the flag
IFF_NO_QUEUE that determine if a device gets "noqueue" when the default
qdisc is attached. The tx_queue_len no longer have any effect on
getting "noqueue". The IFF_NO_QUEUE system removed this double meaning
of tx_queue_len.

It is good you bring it up, but I don't see a backwards compatibility
problem with your usage after the patchset.

If I were you, I would now implement a validation check that reported
the problem if not getting into the expected "noqueue" state. Then
when you eventually upgrade to a more recent kernel, you would get
alerted of improper state.
Something like:
noqueue=$(ip link show dev $DEV 2> /dev/null | grep -q "noqueue" && echo "noqueue" || echo "bad")
if [[ "$noqueue" != "noqueue" ]]; then
echo "report-problem";
fi

* [PATCH v3] xen-netback: prefer xenbus_scanf() over xenbus_gather()
From: Jan Beulich @ 2016-11-08 7:45 UTC (permalink / raw)
To: Paul Durrant, Wei Liu; +Cc: xen-devel, netdev
For single items being collected this should be preferred as being more
typesafe (as the compiler can check format string and to-be-written-to
variable match) and more efficient (requiring one less parameter to be
passed).
Signed-off-by: Jan Beulich <jbeulich@suse.com>
---
v3: For consistency with other code don't consider zero an error
(utilizing that xenbus_scanf() at present won't return zero).
v2: Avoid commit message to continue from subject.
